Yeah, maybe I face similar issues like Alfonse, but I kind of think that "visiting twice" the same topic seems to be a workaround.

Btw, I'm using Chrome.

3. If I reply to a post it marks the post unread, but when I check it, the only new thing is really my own post, which is kind of against logic.

Yeah, I kinda reported something similar months ago. If you post the most recent answer in a thread, it immediately appears in "New Posts". It true that your post is new, but notifying you about it in that way doesn't make any sense.

Firefox here as well, so since we already got two implementations I guess it's nothing browser specific.

Using the full site, it's working as expected. I just figured if we have a mobile optimized version, it should not lose information. If you want to view a complete post on the full site, you have to slide across the page a lot if want a readable size.

EDIT: I just noticed, reading posts on the mobile site seems to not mark them as read when checking new posts using the full site again. Just did so on a desktop machine and already read posts were still marked unread.

That's exactly what disturbs me the most.

Are you logged in when viewing the mobile site? If so, this is most likely a bug which I'll report.

I get problems like that. It's more that it seems like there's a lengthy delay between when you read a thread and when the forum decides you've read it. Something like several hours have to pass before a thread or forum is marked as "read" for you.

I'm using Firefox, FYI.

This could be due to the way the new cache works. We are heavily caching the forums so we can keep up to the traffic. I'm going to investigate this a bit more to see if we can fix this.
